Through an analysis of the political structure, fiscal system, and financing mechanisms at the local level in China, this study seeks to investigate the incentives that prompted local Chinese governments to overinvest in the solar photovoltaics (PV) industry. I find that local governments have several incentives to promote economic development by supporting local industries; their support of China’s PV industry illustrates these incentives. Specifically, we find that there are three major incentives for local governments in China to overinvest in the solar PV industry. First, due to the nature of China’s tax policy, local governments have supported the PV sector to increase local revenue. Second, as these industries have become significant sources of local employment, it is hard to stop supporting them now that PV companies are having difficulties. Third, local officials seek promotions under the economic indicator system by gaining higher GDP. PV companies have been very helpful in contributing to local economic growth, thereby advancing the careers of government officials. Farsighted provinces like Jiangsu used the strength of their existing industrial base and favorable geographical location (proximity to ports) to attract visionary innovators and investors for building their PV manufacturing bases. Thanks to the distorted local political and economic incentives in China, this early wave of PV industry investments preceded a flood of imitating local governments that sought to expand their own PV manufacturing. This uncoordinated, irrational exuberance stemming from distorted, bottom-up local incentives has led to the massive PV manufacturing overcapacity in China. / text

Rural renewable electrification programs are increasingly being used as a means of providing the rural poor in developing countries with access to electricity. Those programs have varied significantly in design and implementation, as well as in their degrees of success. The explanations for the lack of success and the non-sustainability of the earliest programs are widely accepted as these tended to be technical demonstration projects that relied totally on funding from donor organisations or governments. These projects ignored or overlooked the vital question of how ongoing operational, maintenance and replacement costs would be met. Many genuine programs, however, also met with limited success and much effort has been invested in attempting to understand the reasons for this lack of success. To increase the rates of success of these programs, best practice guidelines were developed. Despite these efforts, many programs have continued to meet with limited success. These points required better explanations of the reasons for program success and failure, which requires a greater understanding of these programs. This thesis looks more closely at solar PV electrification programs being undertaken in the Asia-Pacific region to understand why some programs continue to be more successful than others. It aims to understand the decisions behind the planning and implementation of the programs and the reasons that are being implemented in the way that they are, the selection of program objectives, the actual benefits of the programs the and causes of any factors that contribute to their apparent success or lack of success. This understanding is obtained by undertaking in-depth comprehensive field surveys to obtain the views of all program stakeholders. The outcomes of these field surveys are then used to develop a comprehensive set of success criteria and a set of indicators that can be used to measure the success of rural renewable electrification programs. A roadmap that could be followed by the program planners and implementers to ensure program success is also provided.

This thesis describes fundamental biological characteristics of soybean. Main topic of the thesis is finding resistence of twelve soybean varieties to bacterial blight. Virulence of four Pseudomonas syringae pv. glycinea isolates was tested in laboratory conditions to find isolates with the highest virulence, which were then used for testing of selected soybean varieties resistance to this patogen. The highest virulence was found in Šumperk 112 isolate and Žabčice isolate. These isolates were used for testing of soybean varieties resistance. The lowest resistance was found in Moravians variety, low resistance was found in Laurentiana variety and Bru-nensis variety. High resistance was found in Gallec variety and Chinese NM3 variety.

Após a obtenção do EPS e do LPS, respectivamente, pelo método de precipitação em etanol 95% e pelo método que consistiu na fervura seguida de extração com fenol 90%, foram imunizados coelhos da raça Nova Zelândia, com três meses de idade. Os anti-soros produzidos foram avaliados pelos testes de aglutinação, precipitação em gota e imunodifusão dupla de Ouchterlony (IDD). Verificou-se pelos testes de aglutinação e precipitação em gota baixos títulos, 1:16 e 1:32. O teste de IDD, além de mostrar-se mais sensível que o teste de aglutinação e precipitação em gota, constatou diferença antigênica entre os isolados xcc1 e xcc2, e entre as frações EPS e LPS da célula bacteriana. Diante dos baixos títulos obtidos, 1:16 a 1:64, concluiu-se que o EPS e o LPS de X. campestris pv. campestris, utilizados na produção de anti-soro levaram à produção de pequena quantidade de anticorpos, nas condições em que os ensaios foram realizados. / Two Xanthomonas campestris pv. campestris isolates, xcc1 e xcc2, were used to obtain two cell fractions, exopolysaccharide (EPS) and cell wall lipopolysaccharide (LPS). Both of them were used to evaluate immunogenicity (antibody production) in New Zealand rabbits and serological specificity. The methods used were agglutination, precipitation and Ouchterlony Double Diffusion (ODD). Low titles were observed through agglutination and precipitation tests. ODD test was more sensitive than both agglutination and precipitation tests and antigenic differences between xcc1 e xcc2 isolates and between bacterial cell fractions EPS and LPS was found. The low titles showed that both X. campestris pv. campestris EPS and LPS were not good for antiserum production in the worked conditions. / Dissertação importada do Alexandria

abstract: This study evaluates two photovoltaic (PV) power plants based on electrical performance measurements, diode checks, visual inspections and infrared scanning. The purpose of this study is to measure degradation rates of performance parameters (Pmax, Isc, Voc, Vmax, Imax and FF) and to identify the failure modes in a "hot-dry desert" climatic condition along with quantitative determination of safety failure rates and reliability failure rates. The data obtained from this study can be used by module manufacturers in determining the warranty limits of their modules and also by banks, investors, project developers and users in determining appropriate financing or decommissioning models. In addition, the data obtained in this study will be helpful in selecting appropriate accelerated stress tests which would replicate the field failures for the new modules and would predict the lifetime for new PV modules. The study was conducted at two, single axis tracking monocrystalline silicon (c-Si) power plants, Site 3 and Site 4c of Salt River Project (SRP). The Site 3 power plant is located in Glendale, Arizona and the Site 4c power plant is located in Mesa, Arizona both considered a "hot-dry" field condition. The Site 3 power plant has 2,352 modules (named as Model-G) which was rated at 250 kW DC output. The mean and median degradation of these 12 years old modules are 0.95%/year and 0.96%/year, respectively. The major cause of degradation found in Site 3 is due to high series resistance (potentially due to solder-bond thermo-mechanical fatigue) and the failure mode is ribbon-ribbon solder bond failure/breakage. The Site 4c power plant has 1,280 modules (named as Model-H) which provide 243 kW DC output. The mean and median degradation of these 4 years old modules are 0.96%/year and 1%/year, respectively. At Site 4c, practically, none of the module failures are observed. The average soiling loss is 6.9% in Site 3 and 5.5% in Site 4c. The difference in soiling level is attributed to the rural and urban surroundings of these two power plants. / Dissertation/Thesis / M.S.Tech Engineering 2013

Domestic and community low carbon technologies are widely heralded as valuable means for delivering sustainability outcomes in the form of social, economic and environmental (SEE) policy objectives. To accelerate their diffusion they have benefited from a significant number and variety of subsidies worldwide. Considerable aleatory and epistemic uncertainties exist, however, both with regard to their net energy contribution and their SEE impacts. Furthermore the socio-economic contexts themselves exhibit enormous variability, and commensurate uncertainties in their parameterisation. This represents a significant risk for policy makers and technology adopters. This work describes an approach to these problems using Bayesian Network models. These are utilised to integrate extant knowledge from a variety of disciplines to quantify SEE impacts and endogenise uncertainties. A large-scale Object Oriented Bayesian network has been developed to model the specific case of solar photovoltaics (PV) installed on UK domestic roofs. Three specific model components have been developed. The PV component characterises the yield of UK systems, the building energy component characterises the energy consumption of the dwellings and their occupants and a third component characterises the building stock in four English urban communities. Three representative SEE indicators, fuel affordability, carbon emission reduction and discounted cash flow are integrated and used to test the model s ability to yield meaningful outputs in response to varying inputs. The variability in the percentage of the three indicators is highly responsive to the dwellings built form, age and orientation, but is not just due to building and solar physics but also to socio-economic factors. The model can accept observations or evidence in order to create scenarios which facilitate deliberative decision making. The BN methodology contributes to the synthesis of new knowledge from extant knowledge located between disciplines . As well as insights into the impacts of high PV penetration, an epistemic contribution has been made to transdisciplinary building energy modelling which can be replicated with a variety of low carbon interventions.

This master thesis examines if a PV system in “norra Djurgårdsstaden” (Stockholm) can be optimized by the addition of a battery storage system. Both in terms of increasing the usage of the produced PV energy and also (partly as a consequence) becoming more efficient and environment friendly. Simulations were run in both MATLAB and PVsyst. The simulations were based on measured data - PV production and consumption - and different scenarios were examined. Though the central aspect was to maximize the amount of PV energy used, simulations for peak shaving and a combination of the two were also examined.  The major differences between simulation in MATLAB and PVsyst were firstly, the fact that the input for consumption was monthly in PVsyst and hourly measurement (given by Incoord) was used in MATLAB and secondly, that different types of battery types had to be used. The battery type used in the MATLAB simulation was a NiMH battery from a company called Nilar. This battery type has the ability to be rejuvenated and thereby extend its lifetime. This type of battery did not exist as an option in PVsyst. Due to this the result of the simulation was not exactly the same. They were however similar enough to be useful; they showed similar patterns even at points of divergence.  Although the real estate was planned and built to be very energy efficient and environmentally friendly, the integration of a battery storage system was definitely able to optimize the PV system. Of the different integration options examined the most optimal was determined to be when the battery system was fed by the surplus energy from the existing PV system; after it has met momentary consumption needs. At the largest, battery storage system (10 batteries) the primary energy number (EPpet) decreased with almost 8 kWh/m2 - i.e. from 48,2 to just above40 kWh/m2. Self - consumption and self - sufficient was also positively affected by the battery storage with the former going from 59 to 77 % and the latter from 31 to 41 %. Furthermore with around 4 batteries in the battery storage system the EPpet decreased such as the real estate entered a higher order of environmental classification.  The battery system will always be an expense, however this expense is lessened by utilizing as much as possible of the PV energy, i.e. when the momentary consumption is met by the PV system before the surplus PV energy is directed to the storage in order to maximize self - consumption.
